This is how you get really annoying restrictions on public networks, because some harmless traffic will inevitably be miscategorized by an overeager firewall/DPI system.

I’m not saying that there should be zero consequences for allowing bad traffic from your network, but there’s a balance, and I would hate a world in which your policy were more common.

Arguably we are already partially living in that world, as some companies are already blanket-banning entire countries, VPNs etc., rather than coming up with more fine-grained strategies or improving their authentication systems to make brute force login attempts harder. It’s incredibly annoying.
